-monium
Latin
Etymology
From Proto-Indo-European *-monyom, from *-mō.
Note that, as in Ancient Greek δαιμόνιον (daimónion), the -o- should be short, but, as in Latin the declension of -mō (e.g. sermō) was contaminated by the nominative case and thus made -mōn- instead of -mon-, this derivation was apparently contaminated also.
Pronunciation
- (Classical Latin) IPA(key): /ˈmoː.ni.um/, [ˈmoːniʊ̃ˑ]
- (modern Italianate Ecclesiastical) IPA(key): /ˈmo.ni.um/, [ˈmɔːnium]
Suffix
-mōnium n (genitive -mōniī or -mōnī); second declension
- Forms collective nouns and nouns designating legal status or obligation from other nouns.
- pater (“father”) → patrimōnium (“inheritance”)
- māter (“mother”) → mātrimōnium (“marriage”)
- testis (“witness”) → testimōnium (“evidence”)
Usage notes
- daemonium, lēmōnium, scammōnium, harmonia etc. are inherited from Ancient Greek.
